To all whom it may concern:

Be it known that I, DONALD H. McPHnnson, a citizen of the United States, residing at Le Boy, in the county of Genesee and State of New York, have invented certain new and useful Improvements in Tools for Removing Tires; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to tools for removing tires, particularly from quick detachable rims having one flange removable and normally retained in place by any suitable means.

It is my object'to generally improve upon the construction of the tools heretofore used for this purpose.

One important object is to obviate the danger of the tool slipping ofl the detachable flange during the operation of advancing the latter to permit the locking ring to be removed.

Another object is to provide for automatically locking the movable part of the tool in its advanced position whereby the detachable flange is held firmly while both of the operators hands may be employed in removing the locking ring.

A further object is to enable the tire to be separated from the looking ring in case it adheres or sticks thereto. This feature of my tool renders it capable of being used for removing clencher tires from solid rims;

Still another object is to adapt the tool for use on rims of various widths.

Further objects will become apparent from the following description.

The invention consists of a yoke adapted to extend below the rim and felly and'having an adjustable bolt on one end adapted to engage the integral flange of the rim,

while on the other end of said yoke there is mounted a longitudinally movable member adapted to engage the clamping ring. The last mentioned end of the yoke has formed thereon a shoulder which engages the under edge of the rim and prevents the movable part from slipping off of the 'is a side view of cordance with my inventlon, a part thereof clamping ring, vanced bysaid movable part. The rim-engaging end of said movable part is equipped with a pivoted lug or projection which may be turned back into inoperative position but whichmay also be extended beyond the end of said movable member and is designed to engage the tire for separating it from the clamping ring before the latter is engaged by the movable member. Said movable part or member is operated by a hand lever carrying two pins, one being fitted loosely in a transverse groove in the lower edge of the movable part, while the other pin is mounted loosely in a vertically elongated transverse groove in the stationary part of the tool. -The first pin rides along thehorizontal base of the passage in the rigid part of the tool in which the 1ongitudinal member is mounted,so that when the lever is moved to cause the second pin to travel toward said movable member in the vertical groove already mentioned, it results in the first pin being advanced, carrying the movable member with it. The upper and outer portion of the wall of the vertical groove is beveled ofl to form a pocket into which the second pin rides at the'end' of the stroke of the lever which advances the movable member. This pocket has the effect of retaining the lever at the end of itsstroke, thereby automatically look ing the movable member in its extended or advanced position.

- The invention also consists in the features of construction and combinations of parts herein described, illustrated in the accompanyi'ng drawing, and pointed out in the appended claims.

7 In the accompanying drawing: Figure 1 a tool constructed in acbeing broken away to showthe arrangement of the pins in their grooves before the movable member is advanced, and a felly, rim and tire being shown in cross section. Fig. 2 is a similar view showing the movable member in its advanced position, and Fig. 31s a vertical cross section on the line m-w of Fig. 1.

as the latter is being ad Referring more particularly to the drawing, 1 designates the yoke of the tool, and 2 the adjusting screw mounted on the end 3 of said yoke and having its end 4 formed into the shape of a saddle for engaging the integral flange 5 of the rim 6. 7 designates the felly. Said yoke is provided with a shoulder 8 adapted to engage the lower edge of the rim; and, within a passage 10 in an extension 11 of said yoke is mounted a longitudinally movable part or member 9. The projecting end of the movable part is formed, as at 12, to fit the external surface of the detachable flange 13.

14 designates the pivoted lug or projection on the movable member for separating the tire 15 from the detachable flange 13 before the latter is advanced to permit .the removal of the locking ring 16, as illustrated in Fig. 2.

The handle is indicated at 17 and the pins carried .thereby are numbered 18 and 19, respectively. The pin 18 is the one which is mounted in the groove 20 formed in the loweredge of the movable member 9, while the pin 19 is mounted in the vertical elongated groove 21 in the extension 11 of the tool.

Referring to Fig. 1, it will be noted that before the movable member or part is advanced, the handle is arranged in a substantially vertical depending position with the pin 19 resting in the bottom of the vertical groove 21. In this position, the pivoted projection 14 just comes in contact with the tire above the detachable flange 13. By moving the handle outwardly and upwardly to the position illustrated in Fig. 2, the pin 19 is caused to ride along the outer wall of its groove 21 until it comes to rest in the pocket formed by the beveled upper portion 22 of said wall. During this operation, the pin 18 is advanced to the position illustrated in Fig. 2, carrying with it the movable memher 9 and, of course, the projection 14 mounted on the latter. It will be readily understood that, as the movable member is advanced, the projection 14 first disengages the tire from the detachable flange and subsequently the end 12 of said member comes in contact with the outer surface of said de tachable flange and advances it until the locking ring 16 is free to be removed. It will be noted that during the operation of the tool, the shoulder 8 remains-in contact with the lower edge of the rim and retains the tool in rigid position.

The specific form of rim, shown in the drawing, is merely given as one type to which my tool is adapted, it being understood, of course, that the tool is applicable to various other rim structures. As'herein before mentioned, the projection 14 may be employed for removing a clencher tire from a one piece rim. It will also be understood that said pivoted projection may be turned back to the position indicated in dotted lines in the drawing when it is not necessary to separate the tire from the detachable flange.
